The ruling on making up the fast of Ramadan on behalf of a deceased person

Question:
I say, Honorable Shaykh! May Allah reward you. My father passed away a few years ago, and he had a debt of fasting the month of Ramadan due to illness. He did not make up the fasts because of the circumstances of his illness until he died. My question is: Is it permissible for his sons or his wife to make up the fasts on his behalf?

Answer:
If he left off fasting because of illness, and the illness continued with him until he died, then he owes nothing; because he did not neglect it. If he left off fasting because of illness and the illness continued with him until he died, then he owes nothing, and it is not made up on his behalf, nor is food given on his behalf, because he did not neglect it. However, if he recovered from the illness and was able to make up the fasts but left off making them up without an excuse until he died, then food is given on his behalf. Food is given on his behalf for every day, one poor person. Yes.
